Definitions

  • DE 36 41 424 A1 discloses moving a partially mounted vehicle in a production process having a transport means to the individual production stations.
  • the partially mounted vehicle is in this instance raised by the transport means by the partially mounted vehicle being raised at corresponding retention points of the chassis of the vehicle.
  • the vehicle test stand has a plurality of wheel receiving members so that for each wheel of the vehicle a wheel receiving member is provided.
  • the wheels of the vehicle and the wheel receiving members of the vehicle test stand are orientated with respect to each other in such a manner that a wheel receiving member is located below each wheel of the vehicle.
  • the vehicle is raised by a corresponding distance by the transport means.
  • the pressing force can be produced by there being fitted to the vehicle test stand at least one vehicle holding-down member which engages on the vehicle and in this instance pulls the vehicle onto the vehicle test stand.
  • This vehicle holding-down member may engage on the vehicle in one or more suitable positions, such as, for example, on the underbody, on the sill, on one or both bumpers, in the region of the front end or the back end of the vehicle.
  • a common lifting unit may also be provided for the wheel receiving members of the vehicle test stand for the wheels of an axle. It is also possible to provide a common lifting unit for all the wheel receiving members of the vehicle test stand.
  • FIG. 1 shows a schematic drawing of a vehicle test stand, in which the wheel receiving members are provided with lifting devices,
  • FIG. 2 shows an embodiment of the vehicle test stand according to FIG. 1 with wheel receiving members which are in the form of top rollers,
  • FIG. 3 shows an embodiment of the vehicle test stand according to FIG. 1 with wheel receiving members which are in the form of dual rollers, and
  • FIG. 4 shows an embodiment of the vehicle test stand according to FIG. 1 with wheel receiving members of which the two wheel receiving members for the wheels of the rear axle are in the form of top rollers and of which the two wheel receiving members for the wheels of the front axle are in the form of dual rollers.
  • the lifting devices 2 and 3 for the wheels of the rear axle are indicated as are the lifting devices 4 and 5 for the wheels of the front axle.
  • the spacing between the lifting devices 2 and 3 and the spacing between the lifting devices 4 and 5 may also be provision for the spacing between the lifting devices 2 and 3 and the spacing between the lifting devices 4 and 5 to be able to be adjusted. These spacings can advantageously be adjusted independently of each other. Consequently, the vehicle test stand can then also be adapted for vehicles which have different track widths at the front axle and the rear axle.
  • FIG. 1 illustrates on the vehicle test stand another clamping element 6 which acts as a holding-down member for the vehicle. Consequently, the vehicle can be pressed onto the vehicle test stand.
  • FIG. 2 shows an embodiment of the vehicle test stand according to FIG. 1 with wheel receiving members which are in the form of top rollers 201 , 202 , 203 , 204 .
  • the top rollers 201 and 202 for the wheels of the rear axle of the vehicle are associated with drive motors 205 and 206 .
  • the top rollers 203 and 204 for the wheels of the front axle of the vehicle are associated with drive motors, of which only the drive motor 207 of the top roller 204 is provided with a reference numeral.
  • the drive motor 207 (and also the drive motor of the top roller 203 without a reference numeral) serve not only to drive the top rollers 203 and 204 in the circumferential direction thereof, but also to adjust a steering angle for the front wheels of the vehicle. To this end, these top rollers can be rotated about a vertical axis.
  • start-up rollers 208 and 209 are provided for the front wheels of the vehicle.
  • FIG. 3 shows an embodiment of the vehicle test stand according to FIG. 1 with wheel receiving members which are in the form of dual rollers 301 , 302 , 303 , 304 .
  • wheel receiving members which are in the form of dual rollers 301 , 302 , 303 , 304 .
  • the associated wheel receiving member 303 , 304 can be rotated about an axle which is orientated perpendicularly. Steering movements can thereby be simulated again.
  • FIG. 4 shows an embodiment of the vehicle test stand according to FIG. 1 with wheel receiving members 401 , 402 , 403 , 403 of which the two wheel receiving members 401 , 402 for the wheels of the rear axle are in the form of top rollers and of which the two wheel receiving members 403 , 404 for the wheels of the front axle are in the form of dual rollers.
  • the dual rollers 403 and 404 can again be rotated about a perpendicular axis in order to simulate steering movements of the vehicle.
  • FIG. 5 shows a flow chart for the method.
  • step 501 the vehicle test stand and the vehicle are orientated with respect to each other in the horizontal plane.
  • the spacings of the wheel receiving members of the vehicle test stand are further adjusted to the wheel base of the vehicle which is intended to be examined and the track width(s) of the vehicle which is intended to be examined.
  • step 502 the wheels of the vehicle and the wheel receiving members are brought into a non-positive-locking interaction. This is carried out by means of a movement of the wheel receiving members and the associated wheels in a vertical direction. A clamping element which may be present is closed.
  • step 503 function tests, measurements and adjustment operations are carried out.
  • step 504 the wheel receiving members of the vehicle test stand are uncoupled from the wheels of the vehicle again. A clamping element which may be present is released again.
  • step 503 all the operations which are already known in connection with other test stands can be carried out again.
  • These possible examinations also include a transposition test of the speed sensors on the wheels of the vehicle.
  • the wheels may in this instance be driven by means of the driven rollers of the individual wheel receiving members. This can be carried out one after the other. Consequently, it can be determined whether the “correct” speed sensor is providing a signal.
  • the wheels can be driven at different speeds (for example, at 5, 10, 15 and 20 km/h). Consequently, it can be checked whether the individual speed sensors each provide the correct measurement value.
  • the possible examination also includes a transposition test of the brake valves.
  • the rollers of the wheel receiving members can be driven in such a manner that different drive torques on the individual rollers are adjusted in order to brake the wheels of the vehicle. It can then be verified whether the wheels of the vehicle rotate in each case at the anticipated speed. In this instance, the different drive torques of the rollers can be adjusted and distributed in such a manner that the yawing moment of the vehicle is minimized.
  • the clamping device the vehicle can be fixed on the test stand.
  • the advantage 10 of examples disclosed herein becomes evident as the secure clamping of the vehicle so that the vehicle does not leave the vehicle test stand in an uncontrolled manner.
